What You'll Learn
The first plastic IV catheter was demonstrated in 1930
The history of IV use is a varied and long one, with the earliest recorded use of intravenous therapy dating back to the 11th century. The first recorded attempt at IV therapy was performed by a doctor caring for Pope Innocent VIII in 1492. The doctor gave the Pope an infusion of blood from three young boys, but unfortunately, all four died.
The practice of injecting fluids into a vein has been around since the 1600s in Europe, coinciding with the Scientific Revolution and major discoveries in science. In the 19th century, IV equipment was made of metal needles, rubber tubing, and glass containers. These materials required cleaning and sterilization between uses, but they paved the way for the infusion of blood, physiologic solutions, and nutritional support.
In 1930, a significant milestone was achieved with the demonstration of the first plastic IV catheter. This development marked a shift towards more flexible and manageable IV solutions. The invention of plastic IV catheters built upon the advancements in transfusion and resuscitative therapies, as well as the adoption of antiseptic techniques in the 19th century.
The 1930s also witnessed Dr. Thomas Latta's discovery that injecting saline into the bloodstream could aid in fighting cholera. Subsequently, Dr. James Blundell utilized transfusions during postpartum hemorrhages and recognized the correlation between the speed of infusion and its success. These advancements, along with the advent of disposable plastic catheters, laid the foundation for modern IV therapy, providing greater control over medication delivery and reducing adverse side effects for patients.
The evolution of IV therapy continued throughout the 20th century, with improvements in blood pressure and heart rate control during surgery in the 1950s, the introduction of total parenteral nutrition in 1958, and the development of flexible IV bags and plastic IV containers in the 1970s. Today, IV therapy remains a widely used treatment for various medical conditions and has revolutionized the way healthcare professionals provide care.

Plastic IV catheters were invented in the 1950s
The development of plastic IV catheters addressed the limitations of their metal predecessors. Metal catheters were rigid and cumbersome, often requiring physicians to insert them. In contrast, plastic catheters were flexible and easier to manage, enabling a shift in this task from physicians to nurses. This evolution led to the establishment of the Intravenous Nursing Society around 1973.
The invention of plastic IV catheters also improved patient safety and comfort. Plastic catheters allowed for long-term treatments without the same risk of introducing microorganisms into the body, thereby reducing the likelihood of inflammation and infection at the insertion site. This innovation provided greater control over medication delivery times and dosages, minimizing adverse side effects for patients.
The 1950s witnessed advancements in IV medication capabilities, including enhanced control over blood pressure and heart rate during surgery with drugs like nitroglycerin and lidocaine. These improvements contributed to more successful patient outcomes. Additionally, the introduction of total parenteral nutrition (TPN) by paediatrician Stanley Dudrick in 1958 enabled successful feeding through infusion rather than oral means, proving crucial for chronically ill or undernourished patients.
The creation of plastic IV catheters in the 1950s was a pivotal moment in the history of IV therapy. This innovation not only improved the ease and flexibility of IV insertion but also enhanced patient safety and comfort. The impact of this development extended beyond the immediate benefits, influencing the establishment of specialized nursing societies and shaping the trajectory of IV therapy for years to come.

IV therapy has been around since the 1600s
The history of IV therapy is a long and varied one, with the practice of injecting fluids into a vein dating back to the 1600s. However, the concept of IV therapy can be traced back to ancient Greek and Roman times, when bloodletting was practised to reduce perceived toxicity in the body. This involved using cupping at various pressure points to draw blood from the body, a method also used by Hippocrates in 400 BC with leeches. The ancient Romans also used plant-based solutions, combining them with wine or other liquids and inhaling or drinking them using a tube.
The first documented attempt at IV therapy was performed in 1492 by a doctor caring for Pope Innocent VIII in Rome. After the Pope suffered a stroke and fell into a coma, the doctor gave him an infusion of blood from three young boys by joining them in anastomosis to exchange blood. Unfortunately, all four died, and the concept of IV transfusion disappeared for over a century.
In the 1660s, the first recorded attempt at a blood transfusion using basic IV treatment took place, involving two dogs. This experiment was unsuccessful, but Sir Christopher Wren soon created the first successful IV infusion device from a pig's bladder and a quill. In 1658, Wren infused a mixture of wine, ale, opium and liver of antimony into a dog's veins, an experiment that was repeated successfully with other infusates.
Out of fear of adverse reactions, blood transfusions were prohibited by the English Parliament in 1668 and the Vatican in 1669, stalling advancements in IV therapy for over a century. It wasn't until 1796 that Dr Philip Syng Physick, later known as the Father of Modern Surgery, became the first to suggest human-to-human transfusions. This was soon followed by a series of human blood transfusions performed by Dr James Blundell, a British obstetrician, in 1818 for the treatment of postpartum haemorrhage.
In the 19th century, cholera outbreaks across Europe propelled the evolution of IV therapy forward. In 1831, Dr William Brooke O'Shaughnessy realised that cholera victims lost large amounts of water and saline from their blood, and that the blood's natural specific gravity had to be restored. In 1876, Dr Sidney Ringer proposed a physiologic solution for perfusion consisting of sodium, potassium, chloride and calcium.
The 20th century saw significant developments in IV therapy, with the first IV solutions commercially made available in the 1930s, paving the way for medications to be delivered by infusion. In 1933, Baxter marketed the first IV solution in a vacuum bottle. The advent of plastic led to dramatic changes in the medical field, including the development of polyvinyl chloride IV catheters, which made IV fluid therapy much easier to administer. Doctors began experimenting with plastic tubes for fluid delivery in the 1940s, and in 1950, Dr David Massa of the Mayo Clinic in Rochester, Minnesota, developed the "Rochester plastic needle". This was the first modern disposable IV catheter device, revolutionising IV therapy by making it safer and more comfortable. By the 1970s, flexible IV catheters made of plastic, Teflon and polyurethane were being used, and IV therapy began to be administered by nurses rather than physicians.

IV therapy was developed over 400 years
The concept of intravenous (IV) therapy can be traced back to the 1600s, when the practice of injecting fluids into a vein was first introduced. However, it was not until the 1900s that IV therapy became widely used, after the development of techniques for safe and effective administration. Today, IV therapy is a fundamental treatment in intensive care units (ICUs) and is used extensively in hospitals. So, how did we get here?
The first recorded attempt at IV therapy was in 1492 when Pope Innocent VIII fell ill and was administered blood from healthy individuals. Unfortunately, this treatment was unsuccessful, and it was not until the 1600s that the practice of IV fluid injection re-emerged. Despite this early start, advancements in IV therapy stalled for the next few centuries due to a lack of modern scientific knowledge and understanding of the human body.
In the 1800s, there were several important developments in IV therapy. In 1796, Dr Philip Syng Physick, later known as the Father of Modern Surgery, became the first to suggest human-to-human blood transfusions. This was followed by Dr James Blundell, a British obstetrician, who performed a series of human blood transfusions in 1818 to treat postpartum haemorrhage. In the 1830s, Blundell used intravenous administration of blood to treat women bleeding during or after delivery, and in 1831, Dr Thomas Latta studied the use of IV fluid replacements for cholera treatment.
The late 19th century saw another significant push in the evolution of IV therapy due to cholera outbreaks throughout Europe. In 1831, Dr William Brooke O'Shaughnessy realised that cholera victims lost large amounts of water and saline from their blood, and that the blood's natural specific gravity needed to be restored. This understanding paved the way for the infusion of physiologic solutions. In 1876, Dr Sidney Ringer proposed a physiologic solution for perfusion consisting of sodium, potassium, chloride, and calcium.
The 20th century brought even more advancements to IV therapy. In the 1930s, IV solutions were commercially made available, and the first plastic IV catheters were developed. These polyvinyl chloride (PVC) catheters were first invented in 1950 by Dr David Massa, who designed a tube that could be placed over a needle and attached to a hub. This invention revolutionised IV therapy, making it safer and more comfortable for patients.
Over the past 400 years, IV therapy has evolved from early experiments with blood transfusions to a widely used medical treatment. The development of plastic catheters in the 20th century was a significant milestone, making IV therapy more accessible, flexible, and easier to manage. Today, IV therapy continues to be a critical aspect of modern medicine, with ongoing research focused on improving its effectiveness and safety.
